I can answer that, I herniated L 4 and L 5 in 92 did not get the proper treatment worker comp sent me back to work LOL, not really, now living in Florida and the Redhead works @ the Mayo clinic and we have I think the best Drs , I have had new MRI showing L 4 and L 5 have been turned to mush and now T 11 and 12 are destroyed . Long story, sorry, but my back is destroyed the only relief I get is exercise pain management and riding my bike every day. The drs said there is no operation to repair the damage it is too extent, they said they could try to fuse the vertabre but there is no gaurantee, sooo I am in pain and wish this on no one, sorry this is so long winded, Capital Jack:s
